+    == Subject ==
+    Add auto word select mode.
+    Mode name is "AUTO_WORD_SELECT".
+    Press 'I' key to entering to AUTO_WORD_SELECT mode.
+    If you want exit mode, press 'I' key again.
+    This mode alway selects current word.
+
+    == Global variables ==
+    :g:auto_word_select_mode_key|
+      The key that entering to AUTO_WORD_SELECT mode.
+      Default is 'I'.
+
+    == About define keymap with AUTO_WORD_SELECT mode ==
+    The example of defining the key-map for the AUTO_WORD_SELECT mode
+    is shown as follows.
+
+    The following definitions are examples of assign behavior that
+    displays the translation result of the word selecting it by 'alc'
+    service by using multi_requester.js for 's' key.

+    == 概要 ==
+    単語を自動選択するモード(AUTO_WORD_SELECT)を追加します。
+    'I'キーを押すことによって、AUTO_WORD_SELECTモードに移行します。
+    このモードを抜けるには、再度'I'キーを押します。
+    このモードでは常に単語が選択されている状態になり、キャレットの
+    移動の単位も単語毎の移動になります。
+    コンテンツ内の単語を頻繁に選択＆検索する場合などに便利です。
+
+    == グローバル変数 ==
+    :g:auto_word_select_mode_key|
+      AUTO_WORD_SELECTモードに移行するためのキーです。
+      デフォルトは'I'です。
+
+    == AUTO_WORD_SELECTモード用のマップの定義について ==
+    このモード用のマップの定義例として、multi_requester.jsを使用して
+    web上の辞書サービスを使用して検索結果を表示するためのマップを
+    定義する例を示します。

+
+    上記の例ではAUTO_WORD_SELECTモードにおいて、単語を選択した後、's'キーを
+    押すと'alc'で登録されているサービスに対して検索を依頼し、その結果を
+    画面下部のバッファに表示します。
+
+    modes.push()は、OUTPUT_MULTILINEモードから抜けたときに、AUTO_WORD_SELECT
+    モードに復帰させるために行っています。
+
+    追加されたモードに対するマッピングはプラグインを読み込んだ後に行う必要
+    があるので、registerObserver()で"enter"のタイミングでaddUserMap()している。

+    multi_requester.jsの使い方については、ソースのコメントや以下の
